A lot has been posted in this thread about "sex trafficking", and while it surely goes on world-wide on a pretty grand scale, I'm just not seeing it here. Sex trafficking is an underground operation. If I were running such an operation, I would be LIVID if my underlings or associates snatched a suburban white female SAHM resulting in nationwide attention/outcry/search/media coverage. LIVID. And the two female hispanics that SP fingered had better be in hiding across the country somewhere, because I would have their hides and then some. No "sex trafficking ring" would want anything to do with this kind of attention. And no one would buy merchandise with this kind of baggage attached. And damaged baggage at that (bruised, shaved head, branded, emaciated).
This crime was PERSONAL. Either because the two female perps share sadistic fantasies of torturing and humiliating a random female; or because one or both of them were enraged with Sherri (or someone close to her) specifically.
After the latest description that one of the female perps was old enough to have gray hair, gang initiation is not likely. That's a young person's game. It also wouldn't have gone on for 3 weeks.
Sooo.....why abduct someone, keep them for 3 weeks, then send them back in horrendous condition? I think they wanted someone ELSE close to Sherri to suffer and Sherri was the tool they used to make that happen. The sheriff talks about the brand being a "message". I think the entire sequence of events was a message. And I'm pretty sure I know who the message was meant for.
